Letters Patent No. 86,214, dated January 26,1869.

IMPROVEMENT IN SELF-*LUBRICATING- CROSS-HEADS FOR STEAMj-ENG-INES.

The Schedule referred to in these Letters Patent and making part of thesame.-

To all whom it may concern:

Be it known that I, ISAAC l-l. GoxGDoN, of Omaha, in the countyofDouglas, and State of N ebraska, have invented a new and improvedSelilLnbi-icating Cross- Head; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable those skilled inthe art to make and use the same, reference beinghad to the accompanying drawings, forming part of this specification.

This invention relates to improvements in crossheads for steam-engines,whereby it is designed to provide an improved means of lubricating them.

In the accompanying drawings- Figure 1 represents a broken plan view ofa crosshead constructed accordingto my improvement;

Figure 2 represents a sectional elevation ofthe same, taken on the linex x of fig. l; and

Figure 3- represents an end View, partly in section.

Similar letters of reference indicate corresponding parts.

1 propose to core out the two wings or slides of the eross-head, for thepurpose of providing oil-reservoirs, A, (or they may be formed in anysuitable 1naniier,) and to connect the same by a passage, B, through thewrist C, into which reservoirs the oil may be supplied, from time totime, through oil-oups D, the air being allowed to escape throughvent-plugs E.

lu the faees of the slides or Wings F, I provide eircular orother-formed recesses, Gr, hzwing connection with the oil-reservoirs,and in these recesses I place blocks, H, of anti-friction material,having dovetail or other-tin'med grooves in their faces, suitable forretaining gaskets, I, of abs(rbent-material, fitted iu the said grooves,so that one portion will bcar against the faces ofthe guides on whichthe: cross-head slides, a free end, K, of the same extending into theoil-reservoirs, for the purpose oftaking up the oil, and deliveringl ittothe guides.

In order toiusure the lubrication ofthe upper flanges I -of thecross-heads, wicks, M, may be carried up from the reservoirs, throughholes in the slides and grooves in the faces of the said flanges,terminating in holes, as represented in fig. 3, for supporting the saidwicks.

The oil wiil flow naturallyto the lower corresponding flanges.

Holes may be made in the wrist leading from the passage B to theexterior, for the purpose of lubricating it.

And in order to facilitate the cleaning ofthe reservoirs of sediment,plugs, N, may be tapped through the shell of the cross-head, at anysuitable places.

It will be obvious that this arrangement will insure a constant anduniform lubrication, without waste of oil, as the iiow may be governedin amount by the size or coxiduetiug-quality of the wicks, and that itmay be applied to cross-heads for all purposes, whether forsteam-engines or other uses.

I claim as` new, and desire to secure by Letters Patent- 1. Thecross-head of a steam-engine, or other mechanism, provided with theoil-reservoirs A, arranged to supply oil to the sliding parts,substantially as herein shown and described.

2. Thecombination, with the slides or flanges of the cross-head, of thegrooved anti-friction blocks H, arranged in recesses in theweariiig-surfacc of said slides or rl-anges, substantially as described.

3. A cross-head, whose wrist is provided with holes leading from itsweariiig-surface to the oilreser\oirs, substantially as herein deseribedand specified.

t. The lubricatiiig-gaskets I, arranged in combination with the groovedblocks H, and communicating with the reservoir A, substantially asspeeied.

5. Ihe cross-head, having the oil-reservoirs A, as described, which areprovided with the plugs N, substantially as specified.
